A group of experts from the University of Cambridge (UK) revealed that our body is more susceptible to infections during certain times of the day. Ava

According to the study a virus can use your biological clock to it’s advantage and attack you when you are at your weakest.

We spoke to Professor Carlo Selmi, head of Rheumatology and Clinical Immunology at Humanitas and professor at the University of Milan. He also broadcasted his opinion on the Italian show, “Heart and Money”.

According to Cambridge scholars, our immune system has its ups and downs during the day. Mornings seem to be our weakest spot, especially after a bad night’s rest. What is your opinion Professor?

I think this study is very interesting, because it explains what we have been supporting for some time. Namely, that the quality of sleep has an anti-inflammatory effect on your immune system.

It also confirms the existence of a relationship between the hormones that make us wake up in the morning (especially cortisol) and our immune system.

The claim that a rest period of 8-10 hours has a positive effect on your immune system is stronger than ever before.


The “cold season” is about to begin. What do you recommend?

“Firstly get the flu vaccination, which over the years has made tremendous progress and is affordable. A second piece of advice that I can give you, is to not be aggressive with this type of infection. Besides, it is usually resolved within a few days.

Finally, I suggest you pay special attention to at-risk individuals (the elderly or people with other diseases) and possible complications, especially bacterial”.


Basic rules like washing hands, and staying away from sneezes or coughs are still applicable, correct?

“Certainly, I believe that these rules for etiquette should always be observed. Let us not forget that diseases of the respiratory tract can also be transmitted during a simple conversation. Even through droplets of saliva. In any case, I always suggest scrubbing your hands often”.
